Does a change in pH affect the growth and survival rate of aquatic plants?
Students determine if changes in pH affect the growth and survival rates of aquatic plants. They evaluate the optimal pH levels for the growth of aquatic plants.
Curated OER
pH Change and Brine Shrimp eggs
Students determine if brine shrimp eggs hatch and develop more readily in an environment which has an acid or a basic pH. They evaluate the pH level which is optimal for the hatching and development of brine
shrimp.

DOES A FLUCTUATION IN TEMPERATURE IFFECT THE GROWTH AND SURVIVAL RATE OF AQUATIC PLANTS?
High schoolers determine if different temperatures effect the growth and survival rates of aquatic plants and evaluate the optimal temperature for the growth of aquatic plants.
Curated OER
Temperature and Brine Shrimp Eggs
High schoolers determine the optimal temperature at which brine shrimp eggs hatch and develop. They evaluate the changes, if any, which occur in a brine shrimp culture at various temperatures.
Curated OER
Creating Pinhole Prints
Ninth graders produce an image from a negative created with a pinhole camera using the provided materials and create a test strip in 5 second increments to determine the exposure time for a final print.
